;; This file adds support for `fontspec.sty' version 2.7i. Starting
|
||
|
|
;; with `fontspec.sty' v2.4, the order of mandatory font names and
|
||
|
|
;; optional font features in related macros has changed, i.e. optional
|
||
|
|
;; argument comes after the mandatory one. This change is now (April
|
||
|
|
;; 2017) implemented in this file. Fontification support retains
|
||
|
|
;; backward compatibility.
